To all whom it may concern:

lBe it known that l, JOHN B. Purvis, a citizen of the United Statesof'America, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in FoldingBeds, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to folding beds and to an arrangement thereofthat insures positiveness and ease of action in opening, compactness ofdesign with possibility of use of the closed bed as a dresser, bookcase,or the like and other features ott advantageous construction whichprovide a structure of good appearance that is both light and strong.

'lhe invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings,

Figure 1 is a plan view, partially broken f away and in section, of abed that embodies features of the invention, in extended position;

Fig. 2 is a view in side elevation,'partially` broken away and insection, of the bed in extended position;

Fig. 8 is a view in perspective showing the bed partially closed;

Fig. 4 is a view in detail showin the connection of side members of thebe with the head board;

Fig. 5 is a view in cross sectionl of the bed in fully closed position;

Fig. 6 is a view in side elevation showing a modification of the bedwhen extended, together with details of another type of oper atingdevice, and

Fig. 7 is a view showing the modification, of the operating device. y

As herein indicated in preferred form, a headboard 1 with the usualcorner posts, and with the upper portion either provided with a mirror 2or arranged as a bookcase or the like, is connected and held in parallelrelation with a footboard 3 by side lazy tongs 4 and 5 and a horizontalset of lazy tongs 6 1vhich lie below the spring rails of the memers.

The side lazy tongs 4 and 5 are severally connected at their respectiveend portion@ by suitable pivot means directly to the corner -posts 7 and8, ot the head, and corresponding members 9 of the foot board. Thehorizontal lazy tongs 6 are pivoted at one extremity 10 to a member 11of the head board and at rtheother end by a pivot 12 to a corresponding.transverse member 13 of the foot-board. The other head extremity 14 ofthe lazy tongs 6 travels in a longitudinal slot 15 of the member 11,while the corresponding member 16 has a pin and slot connectionindicated at 18 to the member 13. As a preferred form of extendingdevice, a crank arm 19 operates a shaft 2O that Y asses through aswiveled bearing 21 an has screwthreaded engagement with a nut 22pivoted to the lazy tongs 6 at the pivotal junction of the cross membersthereof, so that the reciprocation of the nut when the shaft is rotatedin either direction extends and retracts the lazy tongs in afamiliarmanner and thereby carries with it the remainder of thestructure and opens or closes the bed.

ln order to maintain the bed in open position and prevent any possiblecollapse thereof, a pair of side rails are provided each consisting of asection 24 and a correspond- "ing member 25 pivoted respectively to thehead and foot boards, and provided with a lug 27 on the section 25 thatoverlies the section 24 when the rail is extended and thereby forms arule joint which does not break down and which locks the bed when onceextended. The mattress or spring rails 28 on the head and 29 on the footare arranged to carry any suitable spring mattress such as indicated at30 that will collapse and take the form indicated in Fig. 5, therebygiving plent of spacefor the clothing or bedding. 'lF isspace is furthermaintained by the use of brackets 31 to form the connections or pivotsupports for the sections 24 of the side rails. The space above the lazytongs is utilized by the insertion of drawers 32 and 33 in the footboard which is carried back with side panels 35 as indicated, to form acomplete housing for the mechanism of the bed when the same iscollapsed.

If preferred, another form of operating mechanism may be used wherein atransverse shaft 36 with operating handle 37 carries a pair of smalldrums 38 and a larger central drum 39, Cables 40 are each connected to aquadrant arm 41` of one of the sections 24 and wound around one of thedrums 38. The end portion of a cable 43 is attached to the larger drumand then assed directly around a guide pulley 44 to a astenlll@ ingdevice 45 on the head board. The drums are so proportioned in relationto each other that the cables are taut and by this arrangement anyrotation of the shaft 36 by the crank 37 -projects or retracts the headand foot board to or from each other.

As a result of this construction, a folding bed is obtained that is auseful piece of,

furniture when in collapsed condition, is perfectly rigid andnon-collapsible when extended, and that combines strength, lightness andsuret of action with a constructionthat lren ers it sanitary and readilykept in order.

Obviously, changes in the details of construction may be made Withoutdeparting from the spirit of my invention and I do not care to limitmyself to any particular form or arrangement of parts.

What I claim is l. A bed4 comprising a head board and a foot boardmaintained in parallel spaced relation by bottom and side lazy tongs, ashaft rotatable and longitudinally non-reciprorzeaeva cable in a bearingon one of the boards and in screvvthreaded engagement with a nut pivotedto lazy tongs at the middle joint thereof, and folding rails adapted tolock the boards in projected position.

2. A bed comprising a head board and a foot board maintained in parallelspaced relation by bottom and side laz tongs, a shaft rotatable andlongitudinal y non-reciprocable in a bearing on one of the boards and inscrewthreaded engagement with a nut pivoted to lazy tongs at the middlejoint thereof, folding rails adapted to lock the boards in projectedposition, and a cabinet on one of the boards forming a housing for thebed when retracted and also an auxiliary `piece of furniture.

In testimony whereof I afhx my signature in the presence of twowitnesses.
